A bundled launch is when the creator of a coin, or a group working with them, buys a large share of the supply in the first moments of trading using many wallets at once. On the holder list it looks like lots of separate early buyers. In reality it is one team holding one big stash, ready to sell into anyone who buys later.
How a bundle works
When a coin launches, the first buyers get the lowest price. A bundler sets up a batch of fresh wallets, sends each one some SOL, and has them all buy in the same block as the launch or straight after it. Tools exist that package these purchases together so they go through at the same moment, before anyone outside the group can get in.
The result is a holder list that might show 10 or 20 wallets each holding 2% or 3% of supply. Taken one at a time, none of them looks alarming. Added together, one group might control 30% or 40% of the coin.
Why people bundle
The honest reason given is "protecting the launch from snipers" (bots that buy the instant a coin goes live). Sometimes that is true. But a bundle also does three things that work against ordinary buyers:
- It hides concentration. Checkers that only look at the largest single holder see a spread of small wallets instead of one whale.
- It sets up a dump. The bundled wallets bought at the very bottom. Any rise in price is profit for them, and they can sell across many wallets at once.
- It fakes interest. A long list of holders and early buys makes the coin look popular before it really is.
Warning: A bundle can be sold in a few seconds. If the group controls a third of the supply and sells it together, the price can fall by most of its value before you have time to react.
The signs of a bundle
Identical or near-identical bags
The clearest sign. Real buyers spend random amounts: 0.3 SOL, 1.2 SOL, 0.75 SOL. A script tends to buy the same amount in each wallet, so several top holders end up with almost exactly the same percentage. Three or more wallets each holding 2.41% to 2.45% of supply is not a coincidence you see often with real people.
Wallets created just before launch
Fresh wallets with no history, funded minutes before the coin went live, that bought this coin and nothing else.
Common funding source
If you trace where each wallet's SOL came from, bundled wallets often lead back to the same address, or to the same exchange withdrawal at the same time.
Same block, same moment
All the buys happen in the first block or two. You can sometimes see this on a block explorer such as Solscan by sorting the early transactions.
Creator holdings that look small
The creator wallet may hold almost nothing, which looks reassuring. The bundle is how they hold their share without it showing up under their own name.
How we detect bundles
Our grade looks at the top 20 holders from RugCheck's report, after removing liquidity pools, lockers and other market accounts (those are not people). We then look only at wallets holding 1% or more of the supply.
If three or more of those wallets hold near-identical bags, within 0.05 percentage points of one of those wallets' bags, we add 3 points to the coin's score. For example, wallets at 2.31%, 2.33% and 2.35% would count. Three points on its own is enough to drop a coin to a D, and it usually comes with other warning signs that push it lower.
| What we see | Points added |
|---|---|
| 3 or more top-20 holders (each 1%+) within 0.05 percentage points of one of those wallets' bags | 3 |
| RugCheck links 20+ insider wallets, and they are at least 3% of holders or the coin has fewer than 300 holders | 3 |
| RugCheck links 10 to 19 insider wallets, and they are at least 3% of holders or the coin has fewer than 300 holders | 2 |
The insider check catches a different version of the same problem: wallets linked by how they were funded, even when their bag sizes differ. See insider wallets.
What our bundle check can miss
We want to be clear about the limits.
- Randomised amounts. A careful bundler can buy slightly different amounts in each wallet so no three match. Our near-identical test will not fire.
- Bags already moved. If the bundled wallets have already sold or passed tokens on to other wallets, the pattern may be gone by the time we look.
- Wallets below 1%. A bundle spread across 50 wallets at 0.5% each would not count, though it may show up in the insider graph.
- Innocent matches. Occasionally a few real buyers end up with similar bags by chance, particularly on coins where many people bought with round amounts. That is why the bundle check is 3 points, not an automatic F.
How to check a coin yourself
- Open the coin's holder list on DexScreener, Solscan or RugCheck.
- Ignore the liquidity pool (usually the biggest holder, labelled as the pool or AMM).
- Look at the percentages of the next 20 holders. Are several almost identical?
- Click into two or three of the matching wallets. When were they created? Where did their SOL come from? Did they buy anything else?
- Check the RugCheck report for insider networks and any warning about holder correlation.
If you see matching bags from fresh wallets funded from the same place, assume they are one holder. Add their percentages together and ask whether you are comfortable with one party owning that much.
Bundles after launch
Bundling is not only a launch trick. Some groups buy a coin through many wallets later on, to make holder counts look healthier before a promotion, or to build a position quietly before a coordinated push. The same signs apply: matching bags, fresh wallets, shared funding.
